LAMP-BURNER.

' SPECIFICATION forming: part of Letters Patent No. 751,545, datedFebruary 9, 1904. i

Application flea March 6, 1901.

To all whom it may concern:

Be it known that I, ALBERT H. NELSON, a' resident of Lewiston, in'thecounty of Androscoggin and State of Maine, have invented certain new andusefulImprovements' in Lamp- Burners; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. Y

My invention relates to an improved lamp, and more particularly to animproved burner and wick, the object of the invention being to provide aburner Which will be so constructed as to supply a large amount ofoxygen for combustion and so direct its contact with the flame as toinsure the best possible results.

A further object is to provide an improved wick and improved means forextinguishing the flamethereof. Y

A further object is to provide an improved lamp in which the burner-hoodand chimneysupporting base or platform can be swung back to permitcomplete access to the wick and interior of the burner.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in elevation,illustrating my invention. Fig. 2 is a View in section of the same. Fig.3 is a detail view of the wick. Fig. 1 is a View in section of the same,and Fig. 5 is a detail view of the extinguisher-tube.

1 represents an oil -tank of any desired construction and ornamentation,into which the 'threaded plug 2, supporting my improved a suitablespring-catch 9 is provided on the 7 distance.

Serial No..50,121. (No modelJ inclosing the upper end of. tube 9, and iscontracted at .its upper'end to direct .the air. received through thecentral portion of the per forated disk. 4: against the flame at thebottom.

thereof, while the greater portion of the air which passes up throughthe disk, 1 is supplied to the sides and top of; the flame.

In the tube 9 my improved metal wick-tube 11 is mounted and has securedtherein, preferably by: stitching, a fabric wick 12, the

.stitches passing through perforations in the A-casing 10 is prOvidedondisk A,

before putting the wick on the market, the

fabric wick is held in a suitable oil-contain' ing'tank, so as to absorbthe oil, and the tip lighted, the oil taken up'by the wick burningfreely and drying the tip, which latter being porous after being driedby the heat the flame will pass freely through the tip and thoroughlydry it to almost the hardness of stone, making a tip for the wick whichforms an integral part thereof, which will not burn or need trimming,and which will vastly improve thequality and steadiness of the light.

An extinguisher-tube 14 is mounted to slide on the tube '9 and isprovided below disk 4c with outwardly-projecting arms 15, having curvedfinger-holds 16 at their respective ends .to permit the operator toreadily raise the tube 14: to inclose and extinguish the flame of thewick. Y The base portion of the burner is provided with a series ofspring-arms 17 to project into the lamp-chimney and bear outward againstthe same and securely hold it in position.

Various slight changes might be resorted to in the general form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I would have it understoodthat I do not wish to limit myself to the precise details set forth, butconsider myself at liberty to make such slight changes and alterationsas fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a lamp-burner, the combination with a plug and a fixed tubeextending upwardly from said plug, of a series of arms projectingupwardly from said plug, a perforated disk supported by the upper endsof said arms and encircling said fixed tube a short fixed tubeappreciably larger than the first-mentioned tube, and a hood inclosingthe short fixed tube and the upper portion 'of the first-mentioned fixedtube.

2. In a lamp-burner, the combination with a plug and a fixed tubeprojecting upwardly from the same, of a series of arms projectingupwardly from the plug, a perforated disk supported by said. arms andsurrounding said fixed tube, a short tube fixed to the perforated diskand spaced from the first-mentioned fixed tube, a hood inclosing theshort fixed tube and the upper portion of the first-mentioned tube, avertically-movable tube passing the space between the fixed tubes andmeans for moving said movable tube.

3. In a lamp-burner, the combination with a plug, arms projectingupwardly from said plug and a perforated disk supported at the upperends of said arms, of a fixed tube projecting upwardly from saidperforated disk, a tube fixed to the plug passing upwardly through saidfirst-mentioned fixed tube and spaced from the latter, a hood inclosingthe first-mentioned tube and the upper portion of the tube fixed to theplug, and a stationary wick-casing passing through the inner fixed tubeand a wick secured in said casing, said wick having an ineombustibleupper end.

4:. In a lamp, the combination with a perforated disk, and a hoodsupported thereon and hinged at one side thereto, of a wick-tubesupported centrally in said disk, a casing surrounding the wick-tube andinclosed in the hood, a sliding extinguisher-tube mounted on thewick-tube, and outwaully-projecting arms on the extinguisher-tube belowthe disk, bent at their ends to form finger-holds.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

ALBERT H. NELSON.
